9. Allow caps to sit loose for a while before capping off
Where did this idea come from? It doesn't make any sense. If anything, you'll just get more O2 ingress under the loose cap. There isn't enough dissolved CO2 in the beer that you can knock out to displace the O2 in the small headspace.
Doing that isn't adding anything, and is possibly making things worse...
